Data from National Weight Control Registry shows it's way more possible than most people think to lose weight and keep it off. Just ask the registry's 10,000 participants who lost at least 30 lbs. and haven't found it for a year or longer!

In the most recent study, researchers analyzed about 3,000 men and women who successfully maintained their weight for 10 years after an losing an average of lost 69 pounds. Through a questionnaire, participants revealed the techniques for maintaing the figure they worked so hard as:

- Track their food intake
- Count calorie or fat grams or use a commercial weight-loss program to track food intake
- Follow a low-calorie, low-fat diet. They take in about 1,800 calories a day and less than 30% of calories from fat.
- Eat breakfast regularly
- Limit the amount they eat out. They dine out an average of three times a week and eat fast food less than once a week.
- Eat similar foods regularly and don’t splurge much on holidays and special occasions
- Walk about an hour a day or burn the same calories with other activities
- Watch fewer than 10 hours of TV a week
- Weigh themselves at least once a week

It all seems pretty simple, but for some reason, not enough people take advantage of these techniques!

This isn't the first time the 39-year-old's figure has caused controversy. As we reported in January, the American Pie stunner was accused of using Photoshop to make her already narrow waist even smaller.

Reid has admitted to getting plastic surgery in the past to make changes to her abdominal area and breasts -- but the actress asserts that she naturally has a lean shape.
